TECHNICAL FIELD

[0001] The present invention relates to novel pyrrole derivatives and salts thereof. In detail the present invention relates to novel pyrrole derivatives and salts thereof which have antidiabetic activity. In more detail the present invention relates to novel pyrrole derivatives and salts thereof which have antidiabetic activity improving insulin resistance and safely controlling blood sugar level.

BACKGROUND ART

[0002] Recently due to westernization of eating-habit and increase of social stress, the number of patients with diabetes mellitus has been significantly increasing. Diabetes mellitus is a disease as main cause of chronically hyperglycemia and presents the symptom of said disease by lack of insulin or an excess of inhibitory factor for activity of insulin. Namely, diabetes mellitus is characterized as absolute or relative lack of insulin activity. Diabetes mellitus is clinically classified into insulin-dependent diabetes mellitus (IDDM) and noninsulin-independent diabetes mellitus (NIDDM).

[0003] Therapeutic exercise or dietetic therapy is first tried for treatment of diabetes mellitus. In case that decrease of blood sugar is insufficient even by these therapies, therapy by medicine is then tried. As an oral antidiabetic agent, sulfonyl urea (SU agent) is often used. The activity of this agent is based on promotion of insulin secretion in pancreas and therefore hypoglycemia occurs as side effect. Further, it is known that secondary inactivity occurs due to exhaustion of pancreas by plenty uses of a SU agent. On the other hand, thiazolidinedione derivatives for an antidiabetic agent, which was recently found (Diabetes 2 Nihon Rinsho, 725:125-145 (1997)), was paid attention by the reason as an agent which can control blood sugar by new mechanism showing improvement effect of peripheral insulin resistance. However, liver disturbance as significant side effect was reported on these derivatives and said derivatives have a big trouble in safety.

DISCLOSURE OF INVENTION

[0004] The problem to be solved is to provide an antidiabetic agent which improves insulin resistance and is higher in safety.

[0005] The present inventors have extensively studied to find that pyrrole derivatives improve hyperglycemia by improvement of insulin resistance and that it is superior in the safety and useful as an antidiabetic agent. Then the present invention was completed.

In order to obtain an optical isomer of the present compound in pure form, there are for example, optical resolution methods.

[0826] One of the optical resolutions is to make the compound of the present invention or its intermediate form a salt, in an inert solvent (e.g., alcohols, such as methanol, ethanol, 2-propanol, ethers such as diethyl ether, esters such as ethyl acetate, aromatic hydrocarbons, such as toluene, acetonitrile, or a mixture thereof), with an optically active acid (e.g., a monocarboxylic acid, such as mandelic acid, N-benzyloxyalanine, lactic acid, a dicarboxylic acid, such as tartaric acid, o-diisopropilidene tartrate, malic acid, or a sulfonic acid, such as camphor sulfonic acid, bromocamphor sulfonic acid, etc.).

[0827] When the compound of the present invention, its prodrug or its intermediate has an acidic substituent such as carboxyl group, the compound can form a salt with an optically active amine (e.g., organic amine, α-phenethylamine, kinin, quinidine, cinchonidine, cinchonine, strychnine, etc.).

[0828] The reaction for a salt formation is carried out at a temperature of room temperature to the boiling point of the solvent. It is preferable to raise the temperature to around the boiling point of the solvent once to obtain the compound with optically high purity.

[0829] It may be possible to raise the yield by cooling the reaction mixture, if necessary, before collection the precipitated crystals.

[0830] The amount of an optically active acid or amine is about 0.5 to about 2.0 moles to the substrate, preferably about 1 mole. The resulting precipitate is, if necessary, recrystallized from an inert solvent (e.g., alcohols, such as methanol, ethanol, 2-propanol, ethers such as diethyl ether, esters such as ethyl acetate, aromatic hydrocarbons, such as toluene, acetonitrile, or a mixture thereof) to prepare a salt with its optically higher purity. The salt is further, if necessary converted into a free compound.

[0831] The pyrrole derivative of the present invention, or a prodrug thereof can be administered either orally or parenterally. The compound is orally administered in a usual manner. The compound is parenterally administered in the form of local administration, injection, dermal application, or nasal application. The pharmaceutical composition for oral administration or rectal administration includes, for example, capsules, tablets, pills, powders, cachets, suppositories, liquids, etc. The injections is in form of sterile solution or emulsion. The composition for local administration includes e.g., creams, ointments, lotions, preparations for dermal application (patches, matrixes, etc.).

[0832] These formulations are prepared by a conventional method with pharmaceutically acceptable excipients or additives. The pharmaceutically acceptable excipients and additives include carriers, binders, perfumes, buffering agents, viscosity-increasing agents, coloring agents, stabilizing agents, emulsifying agents, dispersing agents, suspending agents, preserving agents, etc.

The compound of the present invention which is mixed with pharmaceutically acceptable excipients, or without excipients can be put in capsules. The cachets are prepare by the same manner as capsules.

The solution suitable for oral administration is prepared by mixing the compound of the present invention with water, perfumes, coloring agents, stabilizing agents, sweetening agents, solubilizing agents, viscosity-increasing agents, if necessary. The solution suitable for oral administration is also prepared by adding the compound of the present invention with a dispersing agent to water to make it viscous.

[0835] The viscosity-increasing agent includes, for example, a pharmaceutically acceptable natural or synthetic gum, resin, methylcellulose, carboxymethylcellulose sodium, or a known suspending agent.

[0836] The preparation for local administration includes the above solutions, creams, aerosols, sprays, powders, lotions, and ointments. The preparation for local administration is prepared by mixing the compound of the present invention with conventional pharmaceutically acceptable diluents and carriers. The ointments or creams are prepared by adding viscosity-increasing agents and/or gel agents to an aqueous or oily base to prepare the preparation.

Example 202

[1220] The compound of Example 1 or the compound of Example 7 was mixed with powdered feed (CE-2, Japan Crea) as to contain the compound 0.1% and the mixture was administered to male db/db mice (7 weeks old) for 2 weeks. On last day blood was taken from tail vein and blood sugar was measured by antosence II (Sankyo-Bayern).

[1221] The value of blood sugar was degreased by 70% in case of administering 0.1% of the compound of Example 1, and by 34% in case of the compound of Example 7, respectively. The total amount of administration of the compound of Example 1, and the compound of Example 7 was 141 mg/kg, and 151 mg/kg, respectively.

Example 203

[1222] The test compounds described in Examples (these compound were made into a free form from a salt form, a sodium salt or calcium salt, if necessary) were dissolved or suspended in 0.5% carboxymethyl cellulose solution. Mice were forced to orally administer the test compound as to administer the total amount of 30 mg/kg or 100 mg/kg to male db/db mice (7 to 8 weeks old) once a day for 2 weeks. On last day, to the blood just taken from tail vein was added perchloric acid to remove proteins and then the blood sugar was measure by glucose CII Test Waco (Wako Pure Chemical Ind.).

[1223] Hypoglycemic activity was calculated as following formula: ${{Hypoglycemic}\quad {activity}\quad (\%)} = {\frac{A - B}{A} \times 100}$
